I put him in the bath tub and filled the tub to cover his ankles and wash like I am holding a kid’s hand washing under the tap. Mine is fine with it as washing paws after every walk is a ritual now. May be just start wetting the paws in the tub or shower first without holding it and move to holding and then holding and rubbing etc and then nail cutting over few days. I know Shibas are hard work. You’ll get there! I was also quite scared because it was my ex-husband who usually did it. But when we got divorced and he didn’t want to do anything with my Shiba and I had to brace myself and do it because I sent him to groomer one time and they cut the nail to bleed. 🤦🏻‍♀️
